JAMES MADISON KING, OF ROCHESTER, MINNESOTA.

WILD PEA AND OAT SEPARATOR.

SPECIFICATION forming part of Letters Patent No. 325,093, dated August25, 1885.

Application filed January 5,1885. (No model.)

1'' 0 all whom it may concern.-

Be it known that I, JAMES M. KING, a citizen of the United States,residing at Rochester, in the county of Olmstead and State of Minnesota,haveinvented certain new and useful Improvements in Wild Pea and OatSeparators and I do declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same, reference being hadto the accompanying drawings, and to letters or figures of referencemarked thereon, which form a part of this specification.

Figure 1 of the drawings is a vertical sectional view of my device. Fig.2 is a side view of the same. Fig. 3 is a transverse sectional view ofthe main frame, taken through the bearings of a pair of oppositerollers. Fig. 4 is a top view of the machine.

The object of this invention is to provide mechanical means for takingwild peas out of all kinds of small grain and rice, and for taking oatsand wild oats out of wheat.

The invention consists in the construction and novel arrangement ofdevices, as hereinafter set forth, and pointed outiu the appended claim.

In the accompanyingdrawings, the letter A designates an uprightframe-work having at the top the hopper B, which feeds at one side ofthe frame upon the inclined board or guide 0. The mixed grain falls fromthis guide 0 upon the first inclined endless apron, D, which is operatedby the rollers E and F, the journals of which are seated in suitablebearings in the frame. The inclination of this apron is low, being aboutfifteen or twenty degrees, or such that while the more elongated grainsare carried upward by the apron the less elongated grains or wild peaswill roll down the inclination and be discharged at the lower end of theapron. The grain carried upward over the head of the apron is dischargedupon the guide 0, which is inclined at a higher angle than that of theapron,andfeeds the grain, with such wild peas or oats as may still betherein, uponfthe second endless apron, D,

which has an inclination similar to that of thefirst apron. Theseparation is effected by this apron in a similar manner to thathereinbefore described, the round or more spherical grains rolling downthe inclination and being discharged at the lower end of the apron,while the more elongated grains are carried upward over the head of theapron. This endless apron is operated by the rollers E and F, which havetheir journals seated in bearings of the frame. Below the head of thisapron is a third guide, 0, which has sufficient angular inclination tofeed the grain to the next apron, D, which is provided with rollers Eand F, and is also similar in its degree of inclination to the aprons Dand D, and acts in a like manner. Thejournals of the rollers E, E, and Eare provided with sprocket wheels or gearing, and are operated by beltIto cause them to turn in the same direction and at the same rate ofspeed.

H indicates a pressurebar, which is pivoted at or near one end to themain frame, and is designed to bear against the belt I at its oppositeend to insure engagement of the latter with the gearing of theroller-journals. Usuall. the guides G, G, and G are formed with uppershelves or ledges, K, which approximate a level, and hold the grain alittle as it is discharged from the hopper and over the heads of theendless aprons, so that it will be fed upon the aprons in an easy andgradual manner. These guides are important, and are designed to give themixture a slight impetus in the opposite direction from which the apronmoves on receipt of grain. Each apron is provided with a rope, roll, orbelt of cloth-such as a--attached to each edge. Each roller-has agroovesuch as b-around it near each end. Said rope, roll, or belt ofcloth is made to run in these grooves for the purpose of guiding theapron and preventing any substance from rolling off sidewise. This isalso important. Each apron is provided with a scraper against the bottomto detach any substance that may adhere thereto.

1 am aware that it is not new to provide a machine for separating peaswith inclined endless carriers and guides adapted to receive the peasfrom the said inclined carriers and discharge them to the adjacent ones,and therefore do not claim such devices only in the specificconstruction hereinafter pointed out.

Having described this invention, what I claim, and desire to secure byLetters Patent, 1s

The improved pea and oat separator herein described, comprising theframe A, having at its upper end the hopper B, the upper guide beneaththe same, the rollers arranged in two vertical rows at the oppositesides of the frame and formed with grooves near their ends, inclinedendless aprons passing over the said rollers and having projectionsworking in said grooves, the guides arranged over the upper ends of theinclined aprons and having their inclined portions extending between thesaid aprons and their ledges K approximately level, and suitable drivingmechanism for said rollers and aprons, substantially as specified.

In testimony where'ofI affix my signature in presence of two witnesses.
